APPARATUS FOR RULING PHOTOGEAPHIC FILMS.

Application filed July 26, 1921. Serial No. 487,633.

Tor all whom t may concern:

' Be yit known that I, IsrDoR Krrsnn, a citizen of the United States,residing at Philadelphia, in the county of Philadelphia and State ofPennsylvania, have invented certain new and useful Improvements inApparatus fory Ruling Photographic Films, of which the following is aspecification.

My invention relates to an improvement in app-aratus for rulingphotographic films.

The accompanying drawing illustrates a device with the yaid of whichihave produced integral polychromatic lscreens on moving picturey filmsof different lengths. Some of theilms are perforated before theproduction of the integral screen and on some of the films I produceintegral screens without first perforating the film.

In the drawing Fig. 1 is a top plan view of the device, with part offilm inserted therein. Fig'. 2 is a transverse vertical section takenvon line 2-2 of Fig. 1. Fig. 3 is a. vertical longitudinal section takenon line 3--3V of Fig. 1. Fig. 4 is a vertical section taken on line ofFig. 1, and Fig. 5 is a fragmentary plan view of part of the film.

In these drawings, 1 is the support or base on which the device used byme is mounted. 2` is the race-plate adapted to guide the film during thepassage, so that the same may not deviate to right or left. Thisraceplate is held in position by the blocks 3-3 lsecured with the aid ofthe screws 4 4 to the support. 5 is the pressure plate, performing theoffice of keeping. the filmwhen passing through the race-plate in thedesiredyfiattened position. This pressure plate is secured tothe raceplate with ,the aid of the adjustable screws 6--6 in conjunction withthe springs 7--7,4 to produce an eXact adjustment of the pressurerequired. The support 1 is either fastened to a working bench directlyor the drawing with legs 8--8. 9 is an angle plate secured to the base 1and provided with a y'cutout' part or machineslide 10. In this machineslide ispositionedV the' carrier 11, supporting and carrying the .cuttervor knife 12; This cutter or knife is shown here as'c'omprising fourseries of cutting knives 13, 13, 13,13. Each series consists of a num,-

ber of knife edges andthe whole series is y of a width, Asubstantiallyequal' to the width of a film from4 perforation to perforation. rPhewidth of each of the knives of'each series corresponds to the widthofthe line "it is is provided, as shown in' desiredto produce on thefilm. ln some of the cutters made, each series consists of from 120 to160 knives, spaced from each other substantially the width of each ofthe knife edges. rPhe cutter is secured to the adjustable carrier 11.141 are the adjustable means as an entirety for raising and lowering thecarrier 11 and thereby the cutter 12. These adjustable means comprisehere the micrometer screw 15, the means 16, here shown as a conventialknob, to manipulate the screw, the dial 17 provided with the gradations18 and the vzero mark 19, having its counterpart on theJ stationaryblock 20.

1n the drawing is also shown'the film 21 in the process of being woundfrom the spool 22, carried through the race plate and' in operativerelation to one of thek series of knives 13, and propelled' by anysuitable means ,23 at whatever speed is found to be preferred under thecircumstances. .f

InFig. 5, 21 is part of a film as an entirety and of this film 211represents the cutout regions and 25 the intervening remaining areas.These unremoved areas are provided, as will hereinafter be more clearlyexplained with a tinted surface 26 and a coating 27. p i

1t should be stated that the pressure plate 5 is provided with anaperture 28, so as to allow the edges of the normally stationary cutterto come intooperative relation with the film proper. l

The mode of operation in producingk the integrai screen issubstantiallyas follows: Assume that Athe film upon which the screen isto be produced is about 200 feet in length (as most of the films areproduced in lengths of 200 or 4100 feet); and yassume also that one (thereverse.) surface ofthe film is, as usual,`coated with gelatine. Thefirst step is to tint the uncoated (obverse) surface with a given color,dissolved in a medium adapted to attack the Celluloid of the fdm. Incoating the film, 1 make use of a dye dissolved in alcohol and addthereto an equal quantity of ether. I carry the film through thedye-bath with the aid of a revolving drumy and afterthel lm has beenpassed through the dye-bath and vhas been dried, the tintedsurface 'iscovered with' a tem! platel of the device. All parts,l including thepressure plate, the cutter etc. are properly adjusted, so that when thefilm is drawn through the race plate the different knives of the cutterWill out into the film in such manner, as to remove the protectivecoating and the tinted part of the surface. The film Will then present asurface With clear lines in intaglio and protected tinted lines inrelief.

With the aid of a drum or similar device the film is then drawn througha second dyebath of a color different from the color of the firstdye-bath, but of a. nature adapted to attack the celluloid novv laidbare.

I use for the second bath a dye dissolved in alcohol and add theretoabout an equal quantity of ether. After drying, this second dye castingthe temporary protective layers upon both the reverse and obversesurfaces of the film are removed With the aid of Water, at a temperatureslightly higher than normal.

Having now described my invention, what I claim as new and desire tosecure by Letters Patent is:
